Carbon nanotube: An indirect ~ 0 eV band gap material
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 2016, Vol 11, Issue 7
Abstract
Thin film of carbon was synthesized from camphor (C10H16O) by CVD technique in hydrogen atmosphere. For the first time it is confirmed the presence of almost zero indirect band gap in addition to its direct band gap.. Carrier concentration with intrinsic carbon is found to be around 1021 n/cm3. It is suggested that unless the zero indirect band gap is increased carbon thin film cannot be used for making a p:n junction. XRD, Raman and SEM analysis are performed.
